Referring now to Figure 16, the parts of moment of torsion transmission system 250 illustrate with the configuration of the assembling along axle 254.In order to the object of reference, spool 240 illustrates on axle 254 with sectional view.In addition, the cross sectional portion of inner housing portion 216 is shown for reference.As also found out in fig. 8, when some parts of moment of torsion transmission system 250 are arranged in inner housing portion 216, some parts of moment of torsion transmission system 250 are prevented any moving axially.Such as, spool 240 and ratchet housing 602 are prevented with the axial direction longitudinal direction of axle 254 (or along) mobile.Under contrast, screwed 4th gear 237 of the first end 620 along axle 254 can rotate around axle 254 and along axle 254 axial translation (owing to being threadedly engaged).In certain embodiments, the wall portion 652 of inner housing portion 216 limits the 4th gear 237 with the axially-movable in the direction away from ratchet assembly 252.

Layout shown in moment of torsion transmission system 250 is also allowed to rotation and the axial translation of axle 254 herein.Especially, the second end 622 of axle 254 can slide through rigid bearing 266, and the first end 620 of axle 254 is disposed in the passage 660 (see Fig. 8) of the inner housing portion 216 of some axially-movable also allowing axle 254.In certain embodiments, the amount of axial translation limits by the feature and other possible features comprising the contact between flange portion 628 and spool 240.

Figure 17 to Figure 26 illustrates the schematic diagram of moment of torsion transmission system 250 and spool 240, so that explanation increases progressively tension, increases progressively the object of the operation of moment of torsion transmission system 250 during loosening and loosening completely.First with reference to Figure 17, moment of torsion transmission system 250 is that wherein shoestring is the configuration loosened completely.More specifically, this configuration is the configuration being wherein passed to spool 240 without moment of torsion from moment of torsion transmission system 250.In this configuration, the 4th gear 237 can be spaced apart with pawl component 600 (being arranged in ratchet housing 602), makes to be passed to pawl component 600 without moment of torsion from the 4th gear 237.In addition, when not having the 4th gear 237 to provide any clamping pressure against pawl component 600 and spool 240, spool 240 is rotatable, and any substantial resistance at first end 670 place not from pawl component 600.In addition, in this configuration, the second end 672 of fish plate 640 and flange portion 628 and spool 640 is spaced apart, makes spool 240 at the second end 672 place also without the successive resistance what rotates.Although the feature of inner housing portion 612 prevents any axially-movable of spool 240, in this configuration, spool 240 can the first direction of rotation or the rotation of the second direction of rotation.As previously described, by secondary winding assembly 260 (not shown), with the first direction of rotation (namely spool 240 biasing is come, shoestring coiling direction) rotate, described secondary winding assembly 260 applies biased torque at the second holding portion 244 place to spool.But this bias force can be just in time enough large to tie slack and can pull on shoestring by wearer and relatively easily overcome to untie it from spool 240 tight.Therefore, spool 240 in this configuration can relative to freely rotating, although will to spool 240 biasing with the slack that reels when there is not the tension force applied spool 240 by shoestring.

As also illustrated in fig. 17, loosen completely in configuration at this, by the contact 259 compressive engagement plate 640 of limit switch assembly 258.The contact of this and fish plate 640 provides continuity to switch, and electric current can be flowed between contact 259.

Figure 18 illustrates the operation of the moment of torsion transmission system 250 when motor 220 (not shown) starts to rotate.At first, motor 220 driven wheel deceleration system 228, makes the 4th gear 237 rotate with the first direction of rotation (being schematically shown by arrow 700).When the 4th gear 237 with first direction of rotation rotate time, the 4th gear 237 due to the thread interface between the 4th gear 237 and axle 254 towards pawl component 600 axial translation (being indicated by arrow 702).4th gear 237 continues to rotate and axial translation, until the rubbing surface 606 of axle sleeve part 604 contacts and compresses the axle sleeve composition surface 614 of pawl component 600.At this some place, the pretightning force from Compress Spring 642 can provide some to pull power to fish plate 640 and flange portion 628 (it is connected), and to stop axle 254 to rotate, and the 4th gear 237 is along axle 254 axial translation.In the frictional force not having this to pull power or another source or when pulling power, axle 254 can tend to rotate together with the 4th gear 237, makes the 4th gear 237 incite somebody to action not axial translation.

Figure 19 illustrates that spool 240 wherein can start to reel the operation of (that is, moment of torsion transmission system 250 is increasing progressively under tension pattern) moment of torsion transmission system 250 in the configuration of shoestring.In the case, motor 220 continues with the first direction of rotation (as arrow 700 schematically instruction) driving the 4th gear 237, although prevent the 4th gear 237 along any further axial translation of axle 254 with the contact of pawl component 600.Therefore, when the 4th gear 237 is rotated further, axle 254 is (as arrow 706 schematically instruction) translation axially, makes first end 620 from spool 240 translation further.When axle 254 axial translation, flange portion 628 compresses against the second end 672 of spool 240, allows bolt 644 to engage the mating holes (see Figure 15) of spool 254.This makes axle 254 and spool 240 lock together, and prevents the relative rotation of two parts.Contact between flange portion 628 and spool 240 prevents any further axial translation of axle 254.At this some place, because the first end 670 of ratchet assembly 252 against spool 240 clamps, the other driving of the 4th gear 237 works with the first direction of rotation (schematically being indicated by arrow 708) rotation spool 240.As long as motor 240 continues driving the 4th gear 237, shoestring can be wound up on spool 240.

Also can find out in Figure 19, when flange 628 towards spool 240 move and fish plate 640 is followed under the power of Compress Spring 642 time, limit switch assembly 258 and fish plate 640 are separated.This destroys the continuity of electric current between contact 259.

Figure 20 and Figure 21 illustrates the close-up schematic view of some parts.For illustrative purposes, schematic shoestring 720 illustrates with spool 240.With reference to Figure 20 and Figure 21, ratchet assembly 252 guarantees that moment of torsion only can be passed to pawl component 600 and spool 240 from the 4th gear 237, but not vice versa.Especially, the unidirectional operation of ratchet assembly 252 prevents the moment of torsion produced by spool 240 from rotating pawl component 600, the 4th gear 237 and final motor 220.In other words, as previously described, ratchet assembly 252 plays load maintaining body, and it prevents spool 240 from by mistake rotating with the second direction of rotation (that is, untiing direction).This layout can help prevent spool 240 back collecting motor 220 when motor 220 stops or exceeding to the moment of torsion that spool 240 applies the moment of torsion applied by the 4th gear 237 pairs of spools by shoestring wherein.

Figure 22-25 illustrates that moment of torsion transmission system 250 is increasing progressively the operation under relaxed mode.In certain embodiments, increase progressively and loosen and can occur in several stage.During the first stage shown in Figure 22 and Figure 23, operation motor 220 is with the second direction of rotation (as arrow 730 schematically instruction) driving the 4th gear 237.This cause the 4th gear 237 with by arrow 732 schematically indicated direction away from pawl component 600 and spool 240 axial translation.When the 4th gear 237 is away from pawl component 600 translation, release the 4th gear 237, clamping force between pawl component 600 and the first end 670 of spool 240.During second stage shown in Figure 24, then the tension force of shoestring cause spool 240 with the second direction of rotation (schematically being indicated by arrow 734) rotation.Because spool 240 and axle 254 physically locked together in this stage, thus axle 254 together with spool 240 with the second direction of rotation (by arrow 736 schematically instruction) rotation.When axle 254 rotates, be threadedly engaged (and resistance of the rotation of the 4th gear 237 provided by gear reduction system 228 and motor 220) between axle 254 and the 4th gear 237 causes the 4th gear 237 towards pawl component 600 axial translation.Final stage shown in Figure 25, the 4th gear 237, pawl component 600 and spool 240 are clipped together, and it prevents spool 240 from further rotating with the second direction of rotation.This three phases can repeat incrementally to undo shoelaces from spool 240 continuously.

Figure 26 illustrates the operation of moment of torsion transmission system 250 under complete relaxed mode (or complete release mode).With reference to Figure 26, motor 220 can drive the 4th gear 237 with the second direction of rotation (by arrow 740 schematically instruction) rotation, until shoestring tension force is enough low and spool 240 is no longer untied.In certain embodiments, the 4th gear 237 can continue to rotate, until the 4th gear 237 meets with the hard stop provided by the wall portion 652 of inner housing portion 216.Because the 4th gear 237 can not translation further, 4th gear 237 is driven by the continuation of motor 220 and causes axle 254 with by arrow 742 schematically indicated direction axial translation, until fish plate 628 no longer locks together with spool 240 (that is, until bolt 644 departs from from the mating holes 650 of spool 240).At this some place, the contact 259 of limit switch assembly 258 touched by fish plate 640, thus completes limit switch continuity, and it causes motor 220 to stop further.Under this spool 240 stays complete relaxation state, and can relative to freely rotating, although some with the first direction of rotation provided by secondary winding assembly 260 be biased.

Secondary winding assembly

Secondary winding assembly can be configured to and operates independent of moment of torsion transmission system in fact.This can allow winding assembly to tighten slack during each stage of the operation of moment of torsion transmission system.Especially, secondary winding assembly can be configured to the slack tightening tensioning member (such as, shoestring), its can the tension of tensioning member, loosen and loosen completely period occur.

Figure 27 to Figure 29 illustrates the schematic isometric view of some part of motor-driven take-up device 160.More specifically, the general operation of Figure 27 to Figure 29 meant for illustration secondary winding assembly 260 during the different operation modes of system.Figure 27 illustrates the configuration that motor-driven take-up device 160 operates under tension pattern.In such a mode, the 4th gear 237 cooperated with moment of torsion transmission system 250 drives spool 240 with the first direction of rotation, and thus shoestring 800 is wound on around spool 240.In such a mode, when spool 240 is driven by a motor, spring member 262 can be wound to spring bearing 264 from spool 240.

Then with reference to Figure 28, when motor-driven take-up device 160 is with complete relaxed mode operation, the tension force of shoestring 800 rotates spool 240 with the second coiling direction and undoes shoelaces 800 from spool 240.When spool 240 is with the second direction of rotation winding, spring member 262 can be untied from spring bearing 264 and to the second holding portion 244 of spool 240.This allows spring member 262 to get back to default configuration, and wherein secondary winding assembly 260 to tend to coiling direction spool 240 biasing to tighten slack.

Then with reference to Figure 29, motor-driven take-up device 160 is to operate under the pattern being wherein supplied to spool 240 without moment of torsion by motor.In addition, slack is formed in shoestring 800, makes shoestring 800 also not apply very high pulling torque to spool 240.In the case, secondary winding assembly 260 provides bias force with the first direction of rotation winding spool 240, because spring member 262 to be untied and on spring bearing 264 from the second holding portion 244 of spool 240.

During by guaranteeing that motor 220 disconnects, slack rolls tightly rapidly, and secondary winding assembly 260 can improve the availability of clamping system 150.This is desirable, and such user can put on article fast or take off article, and need not wait for motor winding slack.In the shown embodiment, this lax winding use is fast stored in the upper and constant force spring be again wound up on one end of shoestring spool of coast spool (freewheeling spool) and has come.But in other embodiments, multiple different element or system can be used for this fast relaxation winding.Such as, in another embodiment, second fractional motor with decelerator-free or light gear reduction unit (light gear reduction) can be used for lax winding.Going back in other embodiments, other spring elements can be used.Such as, in another embodiment, elastomer torsion spring can be used.Going back in another embodiment, gear-driven clock spring can be used.In addition, in other embodiments, spring member can be wound up on the miscellaneous part of tension system.Such as, in alternative shown in Figure 30, spring member 820 is configured to be wound at one end around spool 240, and is wound on around motor 220 at other end place.This optionally arranges that can be motor-driven tension system provides and configure slightly more closely.Except the speed that improvement reels completely and undoes shoelaces, the battery life of the system utilizing motor to reel completely and undo shoelaces can be extremely improved.

Control method

The various methods of the motor-driven tensioning apparatus of automatic operation in response to various input can be used.Such as, after initial tightening of shoe, it is common that shoestring tension force declines fast within a few minutes the earliest used.Some embodiment of clamping system can comprise the equipment arranged for being made shoestring tension force again be adjusted to initial tension by user.In certain embodiments, control unit can be configured to monitoring that the earliest a moment tension force, then readjust tension force to mate initial tension.

Figure 39 is for automatically readjusting shoestring tension force to maintain the schematic diagram of the illustrative methods of the tension force that user expects along with the time.In certain embodiments, some of following steps has been come by the control unit 302 (see Figure 31) be associated with motor-driven tensioning apparatus 160.In other embodiments, some miscellaneous part by clamping system of following steps has come.Will be appreciated that in other embodiments, one or more of following steps can be optional.

In step 502, control unit 302 can determine whether user has completed tension article.In some cases, if do not receive control command (such as, increasing progressively tension order) after the predetermined time period, then control unit 302 can determine that user completes tighten shoe straps.If control unit 302 determines that user has completed tension article, then control unit 302 continues step 504.Otherwise control unit 302 can be waited for, until determined that user has completed tension article.

In step 504, control unit 302 can monitor the tension force (such as, the tension force of shoestring) of clamping system to determine initial tension in predetermined interval.The method for monitoring tension force comprising current sensor and other sensors has previously been discussed above.In some cases, the tension force of average measurement in predetermined interval can be set to initial tension by control unit 302.

Then, in step 506, control unit 302 can determine whether the tension force of clamping system reduces.If no, control unit 302 can wait for and then reappraise tension force whether reduce.Once determine that tension force reduces, then control unit 302 can proceed step 508.In step 508, control unit 302 can increase the tension force of clamping system automatically, until realize initial tension.In certain embodiments, after step 508, control unit can be waited for and in step 506 automatic Evaluation tension force again.In certain embodiments, control unit 302 can be configured to the tension force being automatically detected tension force and automatically reducing clamping system as answer in addition, until realize initial tension.In some cases, control unit 302 can be configured to the circulation change of carrying out tension force, such as to promote blood circulation.
